Water Leaking Into Basement From Front Porch

We ve been having some issues with water leaking into our basement under our front door.
Water leaking into basement from front porch. I m concerned that the leak may be coming from a fault in the concrete itself so i m looking at waterproofing the slab but i m unsure of what product s or techniques to use. There are a number of weatherproofing issues we need to address but the most urgent is the concrete sill under the door which has been crumbling for a while and presumably is the source of our leak. Water seepage from concrete block foundations is a common occurrence and a problem that tends to worsen over time. When bad rain storms hit and the wind blows just right the covered roof offers little protection and the rain leaks into the basement.
The house is in zone 6b. When it rains or i wash the entry deck there are serious leaks into the basement at several points. The water was still leaking through into the basement. In cold climates insulating basement walls also saves energy and reduces your heating bill.
This original concrete slab was not reenforced. The basement is unfinished and the place where the water drips is clearly visible. The water leaking down saturates the wood between the tongue and groove. However it was not long before it started leaking water into the cellar.
You ll just create a potential mold problem. So long as the wood framed porch had a slope built into it allowing it to shed water to the outside of the building any water that penetrated through the tile floor around the waterproof substrate under the tile and around the large corner support column would have just eventually made it to the outside and never touched the wood. Photo of the original porch attached the crack patches are clearly seen. But don t cover the walls with insulation if water is leaking in from outside.
In this post i will cover the reasons why block foundations leak and the how to fix a leaking cinder block foundation wall. During the winter months blowing snow sits on top of the porch then on slightly warmer days it melts and leaks into the basement. The rooms are not finished and i am not sure of the ceilings construction see photos. I have gone over my caulking job and re applied sealant in areas where it seemed thin.
